WEBFeb 11, 2022 · ECG features of atrial flutter. Narrow complex tachycardia. Regular atrial activity at ~300 bpm. Loss of the isoelectric baseline. “Saw-tooth” pattern of inverted flutter waves in leads II, III, aVF. Upright flutter waves in V1 that may resemble P waves. Ventricular rate depends on AV conduction ratio (see below)
WEBECG in atrial flutter. The ECG shows regular flutter waves ( F-waves; not to be confused with f-waves seen in atrial fibrillation) which gives the baseline a saw-tooth appearance. Atrial flutter is the only diagnosis causing this baseline appearance, which is why it must be recognized on the ECG.

What is Atrial Flutter? | American Heart Association
WEBMar 23, 2023 · Atrial flutter is detectable by an electrocardiogram. During atrial flutter, the atrium of the heart beat 250 to 350 times per minute. (The atrium is the term for the upper chambers of the heart.) This heartbeat is much faster than the normal rate of 60 to 100 beats per minute.
WEBSep 21, 2022 · A provider can tell which type of atrial flutter you have based on your electrocardiogram (EKG) results. How does atrial flutter affect my body? When you have atrial flutter, your heart isn’t working as efficiently as it should. Blood clots could form, which could cause a stroke or heart attack.
WEBDec 8, 2022 · Objectives: Identify the role of the re-entrant mechanism in the etiology of atrial flutter. Describe the different pathophysiologies of typical and atypical atrial flutter. Summarize the use of electrocardiogram, echocardiogram and laboratory tests in the evaluation of atrial flutter.
WEBMar 7, 2024 · The ECG hallmark of typical atrial flutter is discordance in flutter wave "direction" between the inferior leads and lead V1. In counterclockwise circuits, flutter waves are directly negative in the inferior leads but are positive in lead V1. In clockwise circuits, the opposite is true.
WEBECG. The diagnosis of atrial flutter is by electrocardiography (ECG). In typical flutter, ECG shows continuous and regular atrial activation with a sawtooth pattern, most obvious in leads II, III, and aVF (see figure Atrial flutter ). Atrial flutter. (Note: Conducted with right bundle branch block.)

Atrial flutter - Symptoms, diagnosis and treatment - BMJ Best …
WEBFeb 14, 2023 · Atrial flutter, in the typical form, is characterised electrocardiographically by flutter waves, which are a saw-tooth pattern of atrial activation, most prominent in leads II, III, aVF, and V1. Atrial rates are typically above 250 bpm and up to 320 bpm.
WEBNov 29, 2005 · Atrial flutter is a common tachycardia (fast heart beat) that results from a rapid electrical circuit in the atrium ( Figure 2 ). Atrial flutter can be caused by scarring in the heart resulting from prior cardiac disease or heart surgery, but it can also occur in some patients with no other identifiable heart problems.
WEBKey Points. Atrial flutter is a rapid regular atrial rhythm due to an atrial macroreentrant circuit. Symptoms include palpitations and sometimes weakness, effort intolerance, dyspnea, and presyncope. Atrial thrombi may form and embolize. Diagnosis is by electrocardiography.
